2 Claims. (Cl. 210-247) This application is a division of our copendingapplication Serial Number 491,434, filed March 1, 1955 and now US.Patent No. 2,953,249.

This invention relates to a filter and separator for liquids, especiallyemulsified liquids, and is particularly adapted for removing contaminantand water from a water in oil emulsion which may be present in suchliquids as JP-4 jet fuel, gasoline, fuel oil, diesel fuel, kerosene andother similar products.

It is an object of the invention to provide a cartridge which has a highdirt holding capacity and which can be readily replaced by a newcartridge when the original cartridge becomes fouled or otherwiserendered inoperative.

Another object of the invention is the provision of a cartridge whichwill efficiently handle liquids under high flow rate.

Another object of the invention is the provision of a filter andseparator horizontal unit for applications where space and heightlimitations are of primary importance.

With the foregoing objects in view, together with such other objects andadvantages as may subsequently appear, the invention resides in theparts and in the combination,

construction and arrangement of parts hereinafter described and claimed,and illustrated by way of example in the accompanying drawing, in which:

FIGURE 1 is a vertical sectional view of a filterdehydrator in which theunit is in a horizontal position;

FIGURE 2 is a vertical sectional view of a water trap adapted to be usedwith the filter-dehydrator unit illustrated in FIGURE 1.

Referring to FIGURE 1 in the drawing which illustrates a horizontalfilter-dehydrator, the reference numeral 111 designates a tank providedwith a wall or partition 113 to form an inlet chamber 115 and aneflluent chamber 117. The cover 119 and clamping means 121 areconstructed in the same manner as illustrated in Patent 2,953,249 exceptfor the vent 123 which is inserted in the top wall 125 of the tank.

The inlet conduit 127 is connected at one end to the inlet chamber 115and at the other end with a pump or other source of fuel under pressure(not shown). An outlet conduit 129 connected to the chamber 117 isprovided in the top Wall 125 of the tank and a drain 131 connected tothe chamber 117 is disposed in the bottom wall 133 substantiallyadjacent the wall 113.

The partition 113 is provided with a concentric, circular boss 135 forreceiving one end of the cage 137. The partition is provided with a web139 having a tapped hole 141 for receiving one end of the rod 143. Thecap 145 has a concentric, circular boss 147 for receiving the other endof the cage 137. The cartridge 85 is constructed in the same manner asshown and described in Patent No. 2,953,249. A cylinder 149 having anupper portion 151 of screen wire and a bottom portion of solid materialto form a trough 153 is disposed around the cage 137 and spacedtherefrom by an inturned flange 154. The cylinder is provided withopenings or holes 155 in the upper portion to prevent formation of airpockets and an opening 157 forming an outlet in the trough. The partsare held in assembled relationship by the rod 143 and nut 159.

3,223,244 Patented Dec. 14, 1955 The cylinder 149 may be provided with awater trap 161 as illustrated in FIGURE 2.

In the operation of the horizontal filter-dehydrator, the fuel includingcontaminants, water and water emulsion, is delivered under pressurethrough the conduit 127 into the chamber 115, through opening 142 intothe interior of the cartridge 85. The cartridge performs the same dualfunction as described in Patent No. 2,953,249. After passing through thecartridge, the liquid flows through the cage 137 to the interior of thescreen cylinder 149 where the Water particles coalesce into large dropsof water and then fall by gravity to the trough 153. The water from thetrough 153 flows through the opening 157 to the bottom of the chamber117 and out the drain 131. The drainage of water may be simplified bymounting the tank on a slight slope of one or two degrees.

The treated fuel flows through the screen 151 into the upper portion ofthe chamber 117 and out the conduit 129.

It is obvious that various changes may be made in the form, structureand arrangement of parts without de parting from the spirit of theinvention. Accordingly, applicants do not desire to be limited to thespecific embodiment disclosed herein primarily for purposes ofillustration; but instead, they desired protection falling fairly withinthe scope of the appended claims.

We claim:

1. In a fuel and water separator comprising a horizontal disposed tank,a vertical partition having an opening and mounted within the tankadjacent one end to separate the tank into first and second chambers,means for positioning within the tank a filter-separator unit includinga coalescer element mounted horizontally with respect to the partitionwith its interior connected for fuel flow with the opening in saidvertical partition, said positioning means including a cylinder havingan upper screen portion pervious to oil and nonpervious to watersurrounding and spaced from the coalescer element, said cylinder havinga lower nonpervious solid portion with an opening at one end for forminga trough to convey the separated water to a predetermined area in thesecond chamber, an inlet means communicating with the first chamber, afuel outlet means communicating with the upper portion of the secondchamber, and a water drain connected to the lower portion of said secondchamber.

2. A fuel and Water separator as set forth in claim 1, including meansdefining a water trap adjacent the opening in the trough.
